As promised in my posting of 1 August , I have established a web page containing information about the trace element chemistry of marine and non-marine ostracod shells. It can be found at: http://www.kingston.ac.uk/~gg_s416/start.html I hope that everone interested in this subject will take a look at the page and send any additional information or comments to me.
